MORRIS RICHARD SINGERMAN, OF NEW YORK, N. Y.

SHOCK-ABSORBER.

Specification of Letters Patent.

Patented Sept. 17, 1918.

Application led September 28, 1917. Serial No. 193,620.

To all whom t may concern:

Be it known that I, MoRRis RioHARD SINGERMAN, a citizen of the UnitedStates, residing in the city, county, and State of New York,'haveinvented a new and useful Shock-Absorber, of

' My invention consists of the provision in an automobile or otherlvehicle of means for supporting the running boardslthereof, and the mudguards when .connected with the latter, whereby the boards areresiliently supported, so that shocks imparted to the sameare absorbed,and the boards are prevented from sagging and rattling.

The invention is satisfactorily illustrated in the accompanying drawing,but the i1n-' portant instrumentalities thereof may be and transversesection thereof.

Simi ar numerals of reference indicate corresponding parts in thefigures.

Referring to the drawings.

1 designates a portion of the frame of the running gear of the chassisof an automob ile or other vehicle, which latter is provided with therunning boards Q, and the mud guards 3, usual in such cases.

4. designates a cross bar which is formed of what is known as an angleiron, its terminals having the adjacent portions of the running boardsseated thereon and riveted or otherwise firmly connected therewith, saidterminals having thereondepressions 5, whereby the top of the vcross baris flush with the tops of the running boards, said depressions alsoforming the shoulders 6 against which the inner sides of the runningboards may abut, thus assisting` in properly locating said boards onsaid' cross .bar and bracing the former in position on the latter, theangle iron cross bar also being strong and durable in its nature,` andfirmly lsu'staining 'the ruiming boards and consequently the mudguardsthereon.

In the-horizontal limb 7 of the bar 4 areA openings through which arepassed freely which the following the vertically-extending rods 8 Whoseupper.

ends are provided with hooks Aor elbows 9 whose side limbs are adaptedto be fitted on the side members 10 of the frame 1, thus suspending saidrods from said members.

Encircling the rods 8 above the cross bar Il are the coil springs 11,which are rested upon the limb 7 of the cross bar and bear upwardlyagainst the nuts 12 which are fitted on adjacent threaded portions ofsaid rods, thus serving to retain said springs in position and to adjustthe tension thereof.

Encireling the rods 8 below said cross bar arethe coil springs 13 whichbear upwardly against the limb 7 of the cross bar and are rested uponthe nuts 14 which are iitted on adjacent threaded portions of said rods,thus serving to retain said springs in position and to adjust thetension thereof.

It will be seen also lthat each upper andl lower spring has its ownmeans for adjusting the tension of said springs independently of eachother, and the rods guide the springs in their motions.

Washers are interposed between the springs and nuts respectively forevident purposes. It will be seen that as the rumv ning boardsl areimposed on the cross bar and the latter is connected with the frame l bythe rods 8, the springs forni resilient cushions for said cross bar,whereby the running' boards and the mud guards also lwill rideresilientlyon said cross bar, and

so shocks that may be imparted to the running boards and also the mudguards rising and falling with the cross bar are absorbed, thuspreventing rattling of said members and sagging thereof especially therunning boards.

When the motion of the running boards is downwardly the springs 13 fornithe resilient cushions for said boards. When the motion of the runningboards is upwardly, the springs 11 form the resilient cushion for saidboards, and thus the motions of the boards producing shocks in eitherdirections are absorbed.

It is evident that should shocks beiniparted to the chassis which issupported on the frame 1, the same will not be imparted to the runningboardsand mud. guards owing to the resilient cushions formed by thevsprings interposed between said frame and the cross bar 1.

' In order to prevent the hooks or 'elbows 9 from being jolted fromv theframe 1, I employ the washer plates l5 which are rested :ign-inst theunderside of the horizontal limbs of the side members l() of said trame,and provided with openings through which the vertical limbs of thelhooks or elbows t) are passed downwardly. 'l`he lower ends of seidvertionllimbs ot' snid hooks or elbows are formed with threads on whichare titted the nuts 1G which when tightened hold said washer plateslirml)7 in position and prevent the (.lisconnect ion ot the hooks orelbows from said platesf and consequently from the frame l.

llavinglthus described my invention what l claim as new and desire tosecure by Letters Patent, is :M

l."l,n n vehicle having a running` board, a bar member ,on which saidboard is mounted, a resilient. support for said meinberaml a resilientlconnection for said bar member with the running geur oli said vehicle,seid bar member having' therein n depression in which the adjacentportion ot the runninboard is seated. said depression forming a shouldeingainst which said portion of the running board abuts.

In a vehicle having n running board, a bnr ou which said board ismounted. a resilient support l'or said bar, a resilient des vice abovesaid board, a rod-lihe member ,tilted l`reel v iu said barulapted toretain unil guide said device -zind support` und Ameans on saidrod-'lilie member l'or connection of the same with n member ol therunning weer of the vehicle, said rod-like 1neinber inving thereon meansfor the individual adjustment 0t the tension of said resilient deviceand support respectvell said rod-like member being common to the upperand lower resilient device und support.

Si. In a vehicle having a running,` board, a bar on which said board ismounted, n, resilient support for said bar, n resilient device abovesaid board, :t rod-like men'iber litted freely in said bar adapted toretain and guide said device and support, and an elbow-lile member onthe upper portion of said rod-like member attachable to thet'rnmesmember ot' the running gear of the vehicle, said rod-like memberbeing common to said resilient support and device.`

l. In a vehicle having a running board, a bar on which said board ismounted, n resilient support for said bar, n resilient device above saidboard, a rod-like member titted freelyY on said bar adapted to retainand guide said resilient device and resilient support common to both`means on said rodlike member adapted for the adjustment of the tensionot said support and deviee indepentlentl)v oll each other. and means onsaid rod-like member attaehable to the lrume ot' the running' geur otthe vehicle.
